    造纸工业脱墨用浮选柱与目前脱墨主要应用的浮选槽不但在结构上有很大不同,而且衡量浮选柱脱墨能力的参数也与浮选槽有所不同,阐述了浮选槽中未涉及的、浮选柱常用的几个特殊浮选参数:油墨粒子斯托克斯值(sk)、气泡携带能力以及浆料的分散指数.并以逆流浮选柱中试系统为基础,通过具体实验数据分析它们对研究浮选柱浮选脱墨行为的作用.研究表明,在一定的范围内,sk值越大,油墨去除量越多,而浮选柱应用时,气泡携带能力和浆料分散指数则有指导其空气流量和浆料流量设定的能力.

    Compared with conventional flotation cell, column flotation has great difference not only in structure, but also in the parameters for evaluating deinking efficiency, such as ink particle sk number,bubble's carrying capacity and pulp dispersion index which are not referred in flotation cell process. These special parameters were expatiated in this paper. Based on the pilot countercurrent column flotation system, the effect of these parameters on the evaluation of flotation deinking process was analyzed through experiment data.
